In general, the probability that x gets a value c, P(x=c), is defined as . the sum of all corresponding outcomes in S (i.e., the sample space) that are assigned to the value . x. Ex. x = # of heads in tossing 2 fair coins. 3. There are 3 ways to display a probability distribution for a discrete r.v.: through a density plot. through a table ...

From the z table, we find the value of z to be 1.960. So the CI is z*SE=.05(1.960)(.0077)= (.035, .065) G. The population proportion p is unknown, and that’s why we want to estimate . it by the sample proportion. E. P-hat is the sample proportion. =X/n=287/350=.82. Since the researchers are testing to determine if more than “half” of all
